- : : This is built into the SDL program and I know of no way to disable it. The

- : prevent the SDL from loading, *no matter what setting you specify on the

- : serial driver that locks the baud rate (of the serial port that the modem
- : is on) when you run the SDL, the SDL *will* fail.

- Ah! That makes more sense. A fossil driver could likely interfere for
- several reasons but that is a good one. I wish you had stated this as
- clearly when you first commented.
